If there were just one video in the field of software and technology which I’ve watched this summer and would really like to recommend, then it’s this one from about a year ago:
Brian Ford: Is Node.js Better?
At the end, he voices some serious concerns about Node.js in the high-end networking arena w.r.t. its single event-loop without threading, and how the Ruby community hit that wall long ago and made different choices. Interesting, also on a technical level.
But this is not really about language X vs language Y (yawn) – it’s about how we make choices in technology. No doubt your time is limited, and you may not even be interested in Node.js or Ruby, but all I can say is: it made me re-evaluate my positions and convictions, taught me about the power of honest argumentation, and got me to read that brilliant book by Daniel Kahneman, titled Thinking ,Fast and Slow (heavy read – I’m halfway).
